How can a lifeguard recognize a swimmer exhibiting signs of chemical burns?

The recognition of a swimmer exhibiting signs of chemical burns is essential for ensuring the safety and well-being of individuals in the water. Key indicators of chemical burns include redness, irritation around the eyes, skin lesions, or noticeable discomfort after entering the water. These symptoms suggest that the swimmer has come into contact with harmful substances, which could often originate from the water itself, especially in pools treated with certain chemicals or in water that may be contaminated.

Understanding how to identify these signs allows lifeguards to respond promptly and appropriately, which may involve removing the swimmer from the water and administering first aid, such as rinsing affected areas with clean water.

The other options do not provide relevant signs of chemical burns. Colorful swimwear and loud cries do not indicate any chemical exposure or burns; they could be associated with a variety of normal swimming behaviors. Excessive splashing and playing typically suggest a swimmer is enjoying themselves and not experiencing distress. Swimming slower than average may describe several situations, such as fatigue or lack of skill, but it does not specifically indicate a reaction to chemicals. These factors help distinguish typical swimming behavior from symptoms of injury or distress.
